This invention relates generally to aerial vehicles of the power driven type and more particularly to aeroplanes and has for its primary object to provide, in a manner as hereinafter set forth, an aeroplane having supplemental or emergency power means to be brought into use in case of failure of the conventional power means for maintaining the aeroplane in flight until a safe landing can be made.

Other objects of the invention are to provide an aeroplane of the character described which will be simple in construction, strong, durable, efficient and reliable in operation and which may be constructed at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a view in perspective of an aeroplane in accordance with this invention.

Figure 2 is a view in top plan of an aeroplane with portions thereof broken'away and showing diagrammatically the supplemental or emergency power means.

Figure 3 is a view in perspective of a slightly modified form of the invention.

Figure 4 is a view similar to Figure 2 of the form of the invention illustrated in Figure 3.

Referring now in detail to the drawings and to Figures 1 and 2 thereof in particular, it will be seen that the aeroplane is designated generally by the reference numeral 1 and comprises a fuselagev2 and wing 3 of conventional construction.

Suspended from the wing 3 in the usual manner on opposite sides of the fuselage 2 is a pair of conventional power plants in the form of radial internal combustion engines 4 which drive the air screws 5.

Also suspended from the wing 3 on opposite sides of the fuselage 2 and in longitudinal alignment with the engines 4 are the generators 6 which are driven by the air actuated propellers 7 which are operatively mounted serial No. teases.

thereon-L The -.generators 6 areelect-rically connected with astorage battery 8 located at any desired; point in the aeroplane, suitable switches-being interposed in the circuits {between the generators and the battery, as illustrated to advantage in Figure 2 of rthe Conductor drawings.

wires which comprise theicircuit between-the electric motor :11 and the battery 8 are designated bythe reference numeral113 and a-lswitch 14L is interposed in this circuit.

In operation, v when the aeroplane ,is in fl g t and I b in n tional engines 4, the

Should either or fail, the switch leis closed by thepi'lot or another person in the aeroplane. to energize emergency electric motor the supplemental or 11;, thus maintaining the aeroplane in flight, the fmotor 11, of course, driving the-air screw 12.

'In the form ofthe in Figures plane is of the single invention illustrated ,3 and Lof the drawingsflhe aero- -motored type and is designated generally by the reference numeral ,15. The aeroplane 15, comprises; the

usual fuselage 16, and

the wing 5 l7iofconventional construction together with a .radialinternal combustion engine .18 located ,in the nose ofthe fuselagellfi whichrdrives the air screw 19. The engine 18v is theconventional power plant ofthe aeroplane.

Mounted on top of the fuselage 16 on the ,forwardportion of-said fuselageis a genera- ,tor 20 which propeller 21. the drawings, connectedwith a batt is drive n byan air actuated cry 22 which may be As best seen in Figured-of y the generator 20 is electrically located at any desired point in the aero plane, the wires comprising this circuit being designated by the reference numeral 23. A switch 24 is interposed in the electric circuit between the generator 20 and the battery 22. More than one battery 22 may, of course, be provided if desired.

Suspended from the forward portion ofthe wing 17 on each side of the fuselage 16 are the electric motors 25 which drive the air screws 26. Conductor wires 27 comprise circuits electrically connecting the electric motors 25 with the battery 22' and switches 28 are interposed in the circuits between the electric motors 25 and the battery 22.

When the aeroplane 15 is in flight and being powered by the engine 18, the air pressure will drive the propeller 21 in an obvious manner for operating the generator 20 which, of course, charges the battery 22. It will thus be seen that the battery 22' may be charged or maintained in a fully charged position at all times when the aeroplane is being powered by the engine 18. In case failure of the engine 18 the switches 28 are closed to energize the electric motors 25 for driving the air screws 26 for maintaining the aeroplane in flight until a safe landing can e made. 7

It is believed that the many advantages of an aeroplane in accordance with this invention will be readily understood, and although the preferred embodiments of they invention are as illustrated and described, it is to be understood that further changes in the de tails of construction and in arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is In combination with an aeroplane including a fuselage and a wing and further inincluding an internal combustion engine suspended from the wing on each side of the fuselage and still further including an air screw operatively connected to each engine for actuation thereby, a storage battery disposed in the aeroplane, a generator suspended from the rear portion of the wing on each side of the fuselage and in longitudinal alignment with the engines, an air actuated propeller connected to each of the generators for operating said generators, air screws, electric circuits connecting the storage battery to the generators in a manner to receive electric current therefrom, an electric motor mounted in the nose portion of the fuselage, an air screw operatively connected to the electric motor for actuation thereby, an electric circuit electrically connecting the electric motor to the battery in a manner to receive current therefrom, and manually operable switches, interposed in each of the circuits.

In testimony whereof I aflix my signature.
